tured at a relatively low, cost as well as one which will requireminimum attention dur-' ing operation and one in which the upkeep willbe relatively small.

Another object of this invention is to provide an advertising deviceembodying an endlessfilm or tape which carries suitable letters orillustrations for expounding the merits of thearticle or articlesadvertised. The letters or illustrations of the film are transparent soas to permit the projection of light rays therethrough and also toprovide means whereby the size of the letters or illustrations will bemagnified upon presentation to view.

Other objects of the invention will appear in thefollowing detaileddescription and in the accompanying drawings wherein:

Fig. 1 is a horizontal section through the improved advertising device.

Fig. 2 is a vertical section through the advertising device on the line2-2 of Fig. 1.

Fig. 3 is'a vertical section through the advertising device taken on theline 3-3 of Fig. 1.

Fig. 4 is a detail view of the taper-tensioning means employed in theadvertising device.

Fig. 5 is a fragmentary detail of the film or tape employed in theadvertising device.

Referring more particularly to the drawing the improved advertisingdevicecomprises a suitable cabinet or casing-1 which has a translucentfront 2. The translucent front 2 is preferably made of frosted orcolored glass, to add aesthetic value to the advertising device and theframe 3 surrounding this front 2 may resemble an ordinary picture frameof any desired artistic design.

Extending rearwardly into the cabinet or casing 1, from the translucentfront 2 is a pyramidal reflector 4, the inner surface of which ispainted a dull black or any desired to advertising deployment driveshaft 14.

dullcolor to prevent the projection of confuslng light rays. The base ofthe pyramidal reflector 4 is equal in size to the panel or front 2 andan incandescent lamp 5 is positioned at the apex of the reflector 4 andgrrazlnged to project light rays into the reflec- The reflector 4 isprovided with slots 6 and 7 in its edgeat directly opposite points andin close proximity to its apex and the indicia bearing tape 8 travelsthrough these slots, being positioned between the light 5 and front orpanel 2, as clearly shown in Figs.

1 and 3 of the drawings.

The tape or film 8 is opaque and has suitable letters or illustrations 9thereon which are transparent. These letters" or illustrations 9 maybecut in the tape to permit the projection of light there-through orthey may be rendered transparent in any well known approved manner so asto allow the light rays, from the lamp 5, to be projected therethrough.owingl'mto the gradual increasing of the size of t e reflector 4 towardsthe transl cent front or panel 2 the size of the letters'orillustrations 9 will be magnified upon the front or panel 2. The tape orfilm 8 travels about a plurality ers 10and a driving pulley 11. Theguiding rollers 10 are arranged to permit the emof a relatively longendless film or tape. The driving pulley-11 is driven from an electricmotor 12 which is carried by the cabinet or casing 1 and connected tothe drive pulley 11 by a countershaft 13 and Suitable power transmittingmeans, such as pulleys and a belt as indicated at 15, is provided fordriving the.

driving shaft 14 from the countershaft 13. The drive shaft 14 has a worm16 mounted thereon which meshes with aworm gear 17 mounted on the shaft18 which carries the drive pulley 11.

One of the guiding rollers 10 is supported by a substantially U shapedbracket 19 which is, inturn, adjustably supported by a threaded stem 20.The stem 20 extends through 1 and has a thumb nut 21 upon its outer endby which the, stem is rotated for adjusting the position of the roller10 carried by the bracket 19 to tension the tape 8. i v

Briefly, the operation of the improved advertising device is asfollows:'

The driving pulley 11 is rotated from the motor 12 which causes movementof the tape of guiding rollor film 8 causing it to pass through theslots 6 and 7 and consequently through the reflector 4. As the tapepasses through the reflector the light rays from the lamp 5 areprojected through the transparent letters or illustrations on the tapecausing the letters or illustrations to be reproduced on the translucentfront or panel 2, and,'owing to the pyramidal shape of the reflector theletters or illustrations will be magnified as they are reflected uponthe front'or panel 2 and as the tape moves through the reflector, theletters or indicia will travel across the front or panel2 starting atone end thereof and traveling across, dlsappearing at the op'posite endas they pass out of the reflector through the slot 6. i

It is, of course, to be understood that the in two of its opposite sideWalls reachingfrom the top to the bottom of the reflector, an endlesstape passing through the slots and of a Width substantially equal to thelengths and means for moving the tape.

In testimony whereof I affix my signature.
